Peter was first given the keys, but then he was allowed to fall into the sin of denying Christ; and so his pride was humbled by his fall. Do not be surprised, then, if after receiving the keys of spiritual knowledge you fall into various evil thoughts. Glorify our Lord, for He alone is wise: through setbacks of this kind He restrains the presumption that we tend to feel because of our advance in the knowledge of God. Trials and temptations are the reins whereby God in His providence restrains our human arrogance.
Let us be sure, then, that God will not give spiritual gifts - the gifts of understanding, of faith, of love, of purity, of prophecy, of working wonders, of power over demons, of insight, of sight of the heavenly world, to him who has gambled with and made evil use, like the Prodigal Son, of the gifts of bodily health, honor, wealth, success among men or knowledge of this material world, or some other skill or capacity.
As earth thrown over it extinguishes a fire burning in a stove, so worldly cares and every kind of attachment to something, however small and insignificant, destroys the warmth of the heart which was there at first.
If your heart has been softened either by repentance before God or by learning the boundless love of God towards you, do not be proud with those whose hearts are still hard. Remember how long your heart was hard and incorrigible. Seven brothers were ill in one hospital. One recovered from his illness and got up and rushed to serve his other brothers with brotherly love, to speed their recovery. Be like this brother. Consider all men to be your brothers, and sick brothers at that. And if you come to feel that God has given you better health than others, know that it is given through mercy, so in health you may serve your frailer brothers.
As a blacksmith can do nothing without the help of fire, however skilled he may be in wielding his tools, so a man should do everything he can on his side to purify his heart, using virtues as tools for this purpose; but without fire of the Spirit, everything he does will remain inactive and useless for his aim, for by itself what he does is powerless to cleanse the soul of its dirt and foulness.
Do all in your power not to fall, for the strong athlete should not fall. But if you do fall, get up again at once and continue the contest. Even if you fall a thousand times because of the withdrawal of God's grace, rise up again each time, and keep on doing this until the day of your death. For it is written, 'If a righteous man falls down seven times' - that is, repeatedly throughout his life - 'seven times shall he rise again' [Prov. 24:16].
If the humbling of oneself before men is needful that one might be exalted before God, and temporal toil is the prerequisite of immortal life, what does it matter if some shake their heads and laugh at your self-abasement?
Have you realized that the world and worldly cares do not hinder in fulfilling God's commandments, when there is zeal and attention? That silence and retirement from the world are useless, if laziness and negligence prevail?
When a man walks in the fear of God he knows no fear, even if he were to be surrounded by wicked men. He has the fear of God within him and wears the invincible armor of faith. This makes him strong and able to take on anything, even things which seem difficult or impossible to most people. Such a man is like a giant surrounded by monkeys, or a roaring lion among dogs and foxes. He goes forward trusting in the Lord and the constancy of his will to strike and paralyze his foes. He wields the blazing club of the Word in wisdom.
God seeks nothing else from us men except that we do not sin; this alone. But this is not a work of law; it is rather a careful guarding of the image and dignity from above. In these things, affirmed in our nature and bearing the radiant garment of the Spirit, we shall abide in God and He in us. We shall be called good, and sons of God by adoption, marked in the light of our knowledge of God.
